Figure 25-26 shows the DTO event condition asserted when there is a boot acknowledge time-out and CMD0 is used.
t1 – Data time-out counter is loaded and starts after CMD0.
t2 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
t3 – Data time-out counter is loaded and starts.
t4 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
t5 – Data time-out counter is loaded and starts after data + CRC transmission.
t6 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
Figure 25-27 shows the DTO event condition asserted when there is a boot acknowledge time-out when the CMD line is tied to 0.
t1 – Data time-out counter is loaded and starts after the CMD line is tied to 0.
t2 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
t3 – Data time-out counter is loaded and starts.
t4 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
t5 – Data time-out counter is loaded and starts after data + CRC transmission.
t6 – Data time-out counter stops and if it is 0, the MMCHS_STAT[20] DTO bit is generated.
